Environmentally friendly bentonite from a mixture of high-quality clays of Russian deposits. It is a product of drying and grinding of clay raw materials from the Biklyansk field. Additional chemicals in the composition are missing. The natural combination of the mineral components of Biklyan clays determines the stability of suspensions based on them to polyvalent aggression of formation waters.
The increased indicators of the structural-mechanical properties of the clay suspension on the basis of PBN make it possible to use it for all-wash operation in the elimination of absorption zones. Bentonitic clay brand PBN can be used as a lightening component of cement slurries.
It is easy to use. It is resistant to polyvalent aggression. Compatible with all components of the drilling fluid. Environmentally friendly. While maintaining storage conditions, shelf life is unlimited.
